Dental injection related nerve injury
The next day after surgery, if you experience persistent numbness, change in sensation (as if your dental injection hasn’t worn off) then you MUST contact your dentist.
Nerve injuries in relation to routine deep dental block injections may occur in 1 in 14,000 cases. 75% of these injuries are temporary and 25% permanent.
If you experience a severe / excruciating pain during the dental injection the nerve injury may have happened at this time. 60% of patients experiencing severe nerve type pin during an injection may be at risk of persistent nerve injury.
You may benefit from taking non-steroidal anti-inflammatories (Aspirin or Brufen) to reduce any nerve related inflammation, in addition vitamins B 12 and Folate may assist minimising damage to your nerve but there is limited medical evidence to support these supplements.
If your injury persists, surgical intervention is not indicated for these injuries, but you can remain on your vitamin supplements and if you are experiencing discomfort and pain you can arrange a consultation with you doctor to discuss prescriptions of Nortriptyline and Pregabalin. Both these medications treat hyperactive or overly sensitive nerves that have been damaged, but they also have many side effects and are contraindicated for some patients
